SYRUP-PEBCOLATOB.

Specification of Letters Patent.

Patented Nov. 23, woe.

Application filed February 25, 1909. Serial No. 479,860.

To all whom it may concern:

Be it known that I, FRANK DE CLERO a subject of the King of Belgium, anda resident of the city of New York, borough of lvlanhattan, in thecounty and State of New York, have invented a new and ImprovedSyrup-Percolator, of which the following is a full, clear, and exactdescription.

This invention relates to syrup percolators such as used for dissolvingsugar to form syrup which filters through into the syrup chamber. Suchsyrups are used as 'a basis for the flavoring syrups used in soda waterand similar beverages.

The object of this invention is to produce a percolator of simpleconstruction in which the sugar can be readily dissolved without cominginto contact with the air, and from which the syrup may be readilywithdrawn from the syrup compartment beneath.

A further object of the invention is to provide an improved filteringbottom for the sugar compartment.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaim.

Reference is to be had to the accompanying drawings forming a part ofthis Specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a vertical section through a syrup percolator constructedaccording to my invention, this section being taken on the line 11 ofFig. 2; Fig. 2 is a plan of the percolator; Fig. 3 is a section taken onthe line 33 of Fig. 2, and illustrating the construction employed tomake thecover of the percolator substantially air-tight; and Fig. 4 is ahorizontal cross section through the percolator taken on the line 4l4 ofFig. 1, this view showing a portion of the filter bottom as broken away.

Referring more particularly to the parts, 1 represents the body of thepercolator, which is in the form of a cylindrical shell disposed in anupright position. The upper edge of this body is formed with an annularfiange 2, upon which there is received an annular gasket 3. This flangeis provided with wedge heads 4 constructed as shown in Fig. 3, andpresenting horizontally projecting bills with inclined lower edges 5.The coverGof the percolator is made removable,

and is provided with openings 7 which cor respond to the wedge heads 4.In placing the cover in position it is lowered down so that the wedgeheads pass through the openings 7, and the oor er is then rotated bymeans of a horizontal handle bar 8, so that the edges of the openingsengage the inclined surfaces 5 and wedge the cover down on the gasket,as will be readily understood. In the lower portion of the body theinner side of the shell is formed with inwardly pro ecting lugs 9, andthese lugs are adapted to support a filter bottom 10. This filter bottomis composed of a lower disk 11 and an upper disk 12. These disks areprovided with a plurality of perforations 13, as shown. The lower disk11 is provided with upwardly projecting posts 14: and these postssupport the upper disk 12. On the upper side of the lower disk 11 afilter blanket or cover 15 of coarse fabric is applied, and the edges 16are turned under the side edge of the disk, as indicated. A filterblanket 17 is applied to the under side of the upper disk 12, and theedge 18 of this blanket is turned over the upper edge of the upper disk,as shown. The upper disk 12 is provided with a handle 19 on its upperside by means of which it may be removed. The disks are large indiameter, so that when provided with their blankets they fit tightlywithin the shell so as to-substantially exclude the passage of a liquidat their edges.

On account of the posts 14: which may be three in number, as "shown, afilter space is formed between the two blankets, and in this filterspace I place raw cotton 20, or a similar absorbent substance. The spacein the body 1 below the filter bottom constitutes a syrup chamber orcompartment 21, and the syrup which percolates through the filter bottomto this chamber can be removed by means of a faucet 22, as shown. Inorder to permit the air to enter the chamber 21 when the faucet 22 isopen, I provide an air tube 23 which communicates with the upper portionof the chamber 21 and extends upwardly at the side of the body to apoint near the upper extremity thereof, at which point the tube is bentdownwardly and provided with an air check valve which will open on aslight reduction of internal pressure in the chamber 21, but whichnormally excludes the atmospheric air. This valve is most convenientlyin the form of a ball 24 which seats in a small opening 25 in the lowerextremity of the valve body, as indicated.

In using the percol-ator the portion of the body above the filter bottomis substantially filled with sugar 26, and water is then poured in untilthe percolator is substantially full. The water then dissolves the sugarand percolates slowly through the filter bottom 10. By excluding the airthe syrup is prevented from becoming too thick, and the syrup whichpercolates through the filter bottom will be found to be highly fluidand clear. When the filter bottom is to be cleaned, access can be had toit by removing the cover, and by then removing the upper disk 12. Theposts let can then be grasped and operate as handles to assist inremoving the lower portion of the filter bottom.

Having thus described my invention, I claim as new and desire to secureby Letters Patent,

A percolator having a body with a filter bottom therein, a substantiallyair-tight cover for said body, the portion of said body beneath saidfilter bottom constituting a syrup chamber, a faucet for draining saidsyrup chamber, and an air vent having a check valve disposed near theupper end of said body opening communication between the atmosphere andsaid syrup chamber.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
